CARCASS SCRAPING, POLISHNG, AND CI'iEANIllAGrV MECHANISM.

ToaZZ whom z't mj/ concern Be it known that I, JOHN W. KOHLHEPI, acitizen of the` United States, anda resident of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Carcass Scraping, Polishing, and Cleaning Mechanisms; and I do hereby de` clare that the following is a full, clear, and' exact description of the same, reierence being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in scraping mechanisms and' particularly to that class adapted for scraping, polishing and cleaning hogs. v It is an object of this invention to provide a carcass scraping machine in ivhich the use of a conveyer necessitating the use of hooks and carriages is eliminated.

It is a further object of this invention to provide a machine in which the carcasses are moved past the scrapers atthe desired rate or may remain in one place in the machine until completelycleaned and in which the carcasses ai'e continuously rotated or turned thereby exposing all' parts to the action of the Scrapers and to provide alscraping device in which it isl practically impossible to dislodge a carcass-while being acted upon by the beaters. I i

It is a very important object of. this 1nvention to provide spiral rolls, drums or cyl-e indcrs or plain rolls oi." drums with spiral rings, bars, bands, etc., secured thereto for supporting the carcasses, jnioving or con.

veying the same past the Scrapers and simultaneously rota-ting or turning the carcasses. i

It isa very important object of this in-4 vention to provide either a rigi'd'spiral roll,

di um or cylinder' adaptedfor use when pass ing carcasses through the machine at certain velocities for instance slow travel and to provide rolls, cylinders or drums having resilient and yielding spiral 'strips or bars secured thereto which ai'e adaptable for moving carcasses rapidly through'the machine and may be set `for any maximum rate oftravel desired for the carcasses so ,2. g that even though thejvelocityof'the rolls 'Specification of Letters Patent.

. provide a device Patented Jari. 19,

should exceed the limit desired for most eficient scraping yet in which the 'resilient or iiexible spirals will yield to prevent the carcasses from moving faster than the desired rate.

It is an exceedingly important object of this invention toprovide a machine of the elassspecified in Which a plurality of spiral rolls having the same or differently formed convolutions thereon are used conjointly for supporting, conveying and rotating the carcasses or in which a roll and conveyer are conjointly used for this purpose.

It is also an important object of this invention to provide a machine in which fiexible scraping mechanisms are employed and in which the scraping mechanisms coact with the aforesaid conveying or moving and rotating mechanism lfor forcing the carcasses through thev machine.

It is also an object of this invention to provide a device of the class specified in which the rotating and moving carcasses are partly submerged in flu-id at a suitable temperature whereby the hair. dirt and refuse are'ivashed oiiq as loosened and in which the cai'cassesare polished and' scraped simultaneously v It is a further object of this invention to provide a device in which the carcasses are, if necessary, further scalded while being acted upon by the Scrapers should they not have been properly scalded in the scalding vat or tanlcbut entirely eliminating the use or". spraying and pumping devices.

It is also an object of this invention to in which the carcasses are delivered by `gravity to the moving and rotating mechanism and a gravity exit therefor a'tter scraping.

It is' a further ooject of this invention to provide a highly etiicient and greatly simpliied machine of both small and great caf `pacity and the capacity depending upon the g Water inlet-b and steam plus bs# j ingkr vat'and is provided with inafter described andmore fully pointed out and defined in the appended claims.

Fig. 6 illustrates the moving and rotating rolls or drums employed in Figs. 3 and 4. Fig. 7 illustratesthe rolls or drums employed in Fig. 5. Fig. 8 is an end view of a device embodyingmy invention in which a roll or drum and conveyer are conjointly used. Fig. 9 is a side elevation thereof. Fig. l0 is a modiiied form of a device embodying my invention having the mechanisms inclined. Fig. 11 is a detail of the wedge blocks.

4As shown in the drawings: A indicates a scalding vat or tank constructed of any suitable material and size and having the rear bottom wall 'a' thereof inclined upwardly and rearwardly. Journaled in the sides of ,Y the tank at the l"upper and lower ends of said inclined wall a are shafts az on which the elevator a3 .is supported. Adja- .cent the rear end 'of said scalding tank A is a water tank B provided with suitable or heatingv fluid linlet b a'nd with a suitable wash out pipe or and comprises a bottom wall b2, side Walls b3 and end walls 294-115 of a height, Width and length to contain the various mechanisms therein.

j The wall b* of the tank B is placed against 4the top of the inclined wall a of the scalda swinging or automatically closing door 66 above the top of the inclined vwall of the scalding tank which is of a length to admit the hog lengthwise therethrough fromy the conveyer a. Rigidly secured to the', side walls b3 and end Wall b4 of said A't'ank- 'is an inclined platform 67 which extends rearwardly from the bottom of the door opening and the lover endthereof is directed horizontally or at' a slightl angle upwardly.

Journaled in the side walls 3 of said tank is avbeat'er-shaft C on which are bolted or `l otherwisel rigidly secured flexible beater arms c constructed of any suitable material such as canvas, chains, rubber or other flexible medium.

" A flat plate/cf ofy suitable length is secured at`the lowerend of the beater arms c? i`s'se :u1edv thereagainst the arms and moving and rotating Said tank B is constructed ofA Isheet metal or any other preferred material l" tends by means of rivets or in any other suitable manner which strengthens the lower end of prevents short bending. Rigidly secured to the outer ends of said beater arms c are a plurality of sets of flexible or rigid blades 03-04-05 having their outer ends curvedoutwardly and as shown ar-` ranged two abreast but obviouslyl any number ma)1 be used in a set. Y

Journaled in suitable bearings in the side walls b3 below and at the rear of the beater shaft C is a roll, drum or cylinder D to which are rigidly secured in any preferred manner bars or plates cl of suitable metal or other materiall which are shown as angle irons secured to the roller by one flange and the other flange is directedv radially out wardly and parallel the axis of the drum.

A suitable driving pulley D is secured to the drum shaft d3 abone end and sprocket wheels`d-ul2 are rigidly secured to the beater shaft C drum D outside and at the opposite side of the tank and a chain d4 is trained there' around which rives the beaters. Above and slightly to the 'rear 4of the center of the roll or drum D just sufficiently for the bars d to pass is a platform d5 which is shown as horizontal to the end wall b5 of the tank and is then inclined downwardly to deliver the scraped and cleaned carcasses by gravity upon the operating table or bench X.

and drum shaft Z3 of the A partition E is secured to the side walls Zr of the tank B above the platform d5- and pivoted thereto is aA door e .curved toward the opposite end'of the tank and providedwith a spring latch e normally lookin .the door in closed position. A cable or cor e2 brained around suitable pulleys tft-cinc is secured to the latch c and eX- within convenient 'reach of an Aattendant-for opening the door vto admit the cleaned carcass through Athe opening in the end wall b5 upon the platform X andif desired a suitable strip of. flexible material e such as canvas or swinging doors may close said exit.

` the constructions illustrated in Figs. 115

land end walls f-f /2 and which is provided with steam, water and clean out pipes and valves as before described.

-Journaled in suitable bearings in the end `Walls of the tank atthe proper height is a beater shaft G extending longitudinally of the tank to which are rrigidly secured liexible beater arms g provided with scrapers g sudhasbefore described. Said beater arms g as shownclearly in Figs. 3 and 4:'

straight edge h which is concaved to conform to the convex surface of the shaft and the opposite side h is inclined at an angle depending upon the desired angularity -of the beaters. The wedges are secured on the shaft between, the b eater arms having their apexes directed as rshown toward the entrance to the machine and bolts rigidly secure the wedges and beaters in oppositely disposed pairs on the shaft as shown clearly in Fig. 4.

J ournaled in the end walls f2 of the tank below the beater shaft Gr are spiral rolls, drums or cylinders K-K each having gudgeons or shafts in the ends thereof which extend through suitable water tight journal boxes beyond the ends of the tank. `Said rolls or cylinders K-K as shown in Fig.

' 6 are constructed of metal, wood, canvas or other suitable material. -The roll or drum K is provided-with a bar, strap `or band lc of metal or other suitable material coiled spirally around the roll in the form of a helix and which extends from. end to end of the roll. The roll or drum K is provided with a bar, strap or plate k2 of metal or other suitable material and is shown as an angle iron which extends longitudinally of the `roll or drum and is curved partly therearound forming a! spiral roll or drum.

The bands, strap`s,\bars, or coils are constructed in two forms namely, rigid spirals or bars which are nade of material such as steel or other non-yielding material and should the machine'operate above a given velocity ofa yielding cylinder may be used such as a s'olld canvas or rubber cylinder and either lyielding or non-yielding ribs.

On thel other hand, in smaller plants, where one hog is operated'on at a time either a metal or other cylinder may be used with either yieldin or non-yielding ribs and the construction or any user may vary to meet l Said wedge blocks asv 'shown in Fig. r11 are provided with a y power.

the exigencies of the specific case. The preferable form of yielding ribs is constructed of s ring steel,' although other ma- .terial may.

e used as is obvious and is sha ed as an ordinary angle iron. The preferable .erm of non-yielding rib used is also of angle iron shape.

Any suitable driving mechanism may be employed but as shown in Fig. 4 and'dottedlines in Fig. 5 sprocket wheels fL--fL--fs-fy are secured on the endsof the drum or roll shaftsv and beaterv shaft respectively and actuate the drums or rolls K and K in the same direction andthe beaters oppositely therefrom as shown by the arrows in Figs. 8 and 5. l

Guards L-L are secured on each side of the-tank and incline downwardly to apomt Yapproximately over the center of the rolls and allow the spirals to nicely clear thesame.

The beater arms g2 shown in Fig.. 5 are not arran ed angularly with the shaft and instead of employing dili'erent spiral rolls or drums both rollers M-M are similar to the spiral roll or drum K before described.

The construction illustrated in Fi s. 8 and 9 vis similar to that already describe except a conveyer and drum act conjointly instead of two drums or rolls.

The tank F is similar to those already described and journaled therein is the beater shaft Jdprovided with beaters j as before describe Journaled in the tank below and to the left of the beaters is the roll or drumv J providedwith bars or blades j which for small capacity machines extend parallel with th'e axis and for large capacity -machines -are spiral in lform as before described.

Tracks R-R on different horizontal planes are rigidly engaged in the tank and incline slightly end of the machine.

Inclined shafts r arejournaled at each end of the machine having suitable sprocket wheels r thereon which actuates the inclined conveyer S which may be of` any suitable type but conveniently is al flight or lag conveyer anda guard T of any suitable kind returnsthe hog 4tothe drum should the beaters force the same up the eonveyer.

A guard bar or rail s shown as an angle iron is rigidly secured by one flange to the track or other suitable place and bears against the lower side of the conveyer and prevents the same fromrunning or slipping oifthe tracks.

Sprocket wheels jZ-j are securedto the beater shaft and drum shaft and a pulley` y" is secured on the end of the drum shaft for connection with a suitable source of upwardly to the delivery An elevatorlsimilar to c heretofore described delivers thev carcasses from the `vat or scalding Vtank onto an inclined platform 117 such as before described and delivers the carcasses by gravity upon the drum and con-` .veyer. v

' In the construction illustrated in Fig. 10 the. tank N is inclined toward the delivery end and is provided with a suitable outlet m at the lower end thereof adapted to de- -liver the refuse and hair therethrough into a receptacle from which it is delivered to any suitable place and a water supply tank N is situated beneath the tank by means of which' water is supplied to clean the carcass by any suitable'means. n

The spiral rollers 0 are inclined longitudinally of the tank as is: also the scraper shaft D and the beater arms B are arranged thereon as'before described with reference to Fig. 3.

The drive is similar to that before described. Y

I The operation is as follows: The construction illustrated-in Figs; 1 and 2 is for a-small capacity machine. The hogs after being suitably scalded in the vat or tank A' are moved upon the elevator a3 which delivers them through the door b and the carcasses move by grav-ity to the end of the platform b7 and upon the roller D. Inasmuch as the bars d are parallel with the axis of the rollerupon rotation thereof the bars at each revolution engage the hog and rotate or turn the same continuously.A The hog is not moved longitudinally inasmuch as the `roll'or drum is not spiral and the Scrapers which lrotate oppositely from the direction of; rotation of the drum whip and scrape the'hair and refuse from the carcass as the same Zis being rotated. The beaters prevent the carcass from being thrown rearwardly from the rotating drum and the rigid door e prevents the carcass from being moved by the beaters forwardly beyond the roll so thatat all times the carcass is conlco tinuously turning in`l position forthe beaters to act continuously on all parts thereof. The water level in the tank may be any preferred height but is shown as slightly above the roller D approximately on a level with the middle of the carcass so that the carcass is lying and lrotating in water which is heated o r not as is found :necessary and the beaters acting thereon not only scrape the bristles therefrom but polish the carcass.

After the carcass is thoroughly cleaned, the `cord c2 1s pulled releasing the catch and openmaatscing the door and the carcass is forced upoli "the platform d andisf delivered by grav nally of the machine. A plurality of spiral rolls or drums of the same kind may be employed or of course one of each construction may be employed acting conjointly. The operation ofthe spiral rollers shown in Figs. 3, 4 and 6 are as follows: The rollerfK rotates as shown by the arrow to the left and the 'barsor spirals k2 striking the carcass constantly rotate or turn the same inwardly upon the roller. K, said roller K rotating in thesame direction the helical spiral forces the carcassA endwise therealong'at a rate dependent upon the number of revolutions per minute made and the roll or drum K also aids in moving the carcass therealong. At the same time the carcasses are being turned and passed through the tank the beaters g2 are acting thereon onall parts of the carcass and inasmuch as the beater arms are of ilexiblematerial the same conform to the carcass and a large surface of .the hog is scraped by each sweep of the sets of blades., Owing to the angularityof the beaters the same strikes the carcass and force it toward the delivery end of the machine thus pulling the carcasses along aiding the rolls and drums.

The guards L-L prevent all possibility of 10b.

the carcasses from beingdisiodged although danger from this source is slight. As before described the water level in the tankA is maintained at the desired height to wash and clean the carcass.

It may be desired according to various circumstances and the mode of drive to use eitherv the rigid spiral rollers or'those having flexible spirals' thereon and the operation in either case is the. same except where 110l fieXible and resilient spirals are used they may be constructed for a maximum speedv at which to pass the carcass through theytank and when the lrevolutions of the rollers' exceeds a certain velocity from carelessness 115 v or other causes the spirals yield and the carcasses thus cannot be forced through the machine at a greater rate than desired; The advantages of this are obvious fdr inhandling the carcasses in large quantities the 120-4 machine is operated at full speed' and should the drive: become too rapid the carcasses nevertheless are passed through the machine ata rate for efficient scraping. Where two spiral rolls of similar construction are 125 used as shown inFig. 5 the operation is similar and both rolls coact in forcing the carcasses therealong as before described.

The construction shown in Figs. 8 'and 9 may be for either small capacity or large de# 130 pending upon the length Aof the machine. For small ca'pacity machines theA beater shafts are slightly longer than the longest hog. The carcasses are delivered to the drum J and .rest thereon and on the con veyer. The drum rotates the hog a's before described and the belt engages on the loose pulley of the conveyor shaft and thus the conveyer is not actuated. As the beaters act oppositely from the rotation of the roller the hog cannot be dislodged rearwardly and the conveyer by its inclination. prevents the carcass from being movedaway from the vbeaters but should this happen the guard T returns the same to be acted upon by the beaters. After the carcass has been cleaned.

the bel* is shifted to the lixed pulley'thereby actuating the conveyer andmoving the carcass out of the` machine. For large capacity machines the conveyor is continuously actuated and the carcasses passed through the machine successively and'contin-uously. The conveyer also inclines upwardly toward the exit end ofthe machine so that thecarcasses may be rotated in Water and also be delivel-ed over the edge of the vat upon a suitable table.

If preferred the operatingmechanisms 'may be inclined as shown in Fig.` 10 thus utilizing gravity and the tank may or may not be inclined. y

It is seen that the usevof spraying devices and pumps is eliminated and that the carcasses are Washed clean as they are rotated continuously in water. Furthermore should the carcasses not be ysuiiiciently scalded for removal of the bristle the carcass may again be scalded in the tank as the Scrapers act thereon.

Many changes of construction may be varied Without departing from the principles of this invention and I- therefor do not desire to limit this application for patent as to details or otherwise than necessitated by the prior art.` y
